BALL-BEARING.

Specification of Letters Patent.

Patented Nov. 23, 1920.

Application filed April 9, 1920. Serial No. 372,581.

To all whom it may concern v Be it known that I, CHRssTIAN K. HonRLn,

.a citizen of the United States, and resident of Waterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Ball- Bearings, of which the following is a specification.

The object of the invention is to provide a. simple and improved form of-bearing of the general type of that disclosed in Patent No. 1,330,579, granted February 10, 1920.

The invention more particularly resides in the novel construction of a sleeve member which is adapted to be fixed to an axle without the use of pins, keys, or keyways, and in the novel construction of bearing cones which are adapted for attachment to the sleeve member.

With these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, andpointed out in the claims hereto .appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departure from the spirit or sacrificing any of the advantages of the invention.

imilar characters of reference denote like or corresponding parts throughout the several figures of the accompanying drawings formin a part of this specification, and upon which,

Figure 1 shows an end view of a portion of a roller skate having one of its wheels shown in front elevation, and another in central vertical section to illustrate the application of my preferred form of bearing thereon.

Fig. 2 is a vertical cross sectional elevation of the bearing and wheel shown in Fig. 1.

Fig. 3 shows a front and side view respectively of one of the bearing cones forming a part of my bearing.

Fig. 4 shows a side and end view of the tubular spacer shown in Figs. 1 and 2, and

Fig. 5 shows a longitudinal section and end view of a modified form of sleeve with which no extra spacer member is required.

Referring in detail to the characters of reference marked upon the drawings, 10 represents the foot plate of a roller skate, 11

a bracket secured upon the underside thereof and 12 a hanger pivotally connected to the bracket. 13 represents an axle which is secured in the hanger and extends outward from each side for the attachment of my improved form of ball bearing, to support the wheels 14. The wheels may be of the usual or any preferred design but each obviously includes a central opening therethrough and two annular race-ways 15 to accommodate the two series of balls 16 upon which the wheels are mounted. The axles of skates of this character are usually round as shown in the drawing and are threaded to receive the nut 17 which secures the wheel with assembled bearing on the axle.

My preferred form of bearing includes an elongated sleeve 18 which is substantially square in cross section and whose ends are flared out to form annular flanges 19 against which the bearing-cones 20 and 21 are held in position. This elongated sleeve being substantially square in cross section, having a hole therethrough of a size so that when shoved on the round axle will form a tight fit that will hold against turning, thus avoiding the necessity of a keyway or pin;

The bearing-cones 20 and 21 are alike in construction and are of a conical formation including a race-way 22 upon one side for theballs which runbetween it and the raceway 15 of the wheel. Eachof these cones is provided with a substantially square central opening 23 to receive and fit upon the sleeve 18 in\a way to be secured thereto and to hold against turning upon the sleeve. The tubular spacer 2 1 which is positioned upon the sleeve and between the inner ends of the bearing-cones to hold the same apart is also provided with a square hole therethrough to shoulder upon the sleeve in a manner to be rigidly heldwith the sleeve and shaft against turning. "The ball raceways 22 of the bearing-cones are smooth to insure the smooth running of the balls therearound when operated by the wheel supported thereon.

as g

may be shoved on and seated against the flange of the sleeve, whereupon the spacer 24 is placed on the sleeve as-shown in Fig. 4 to hold the bearing-cones at fixed dis tances apart. The assembled parts can then 'be positioned in the wheel, and the balls put in the pockets, after which the outer bearing-cone is put on the end of the sleeve, and that end flared out to hold'the parts together and to form theicomplete unit leavingthe wheel loose to run free upon the sleeve.

The sleeve shown in Fig. 5 is provided with a series of shoulders 25 upon the surface of the sleeve 18 which may be formed by punching out the metal as shown and which serves to properly space the cone when positioned thereon. These series of shoulders on each end portion of the sleeve are in annular alinement and serve to be engaged by.="the cones 20 and 21 when positioned and secured thereon by the flaring of the end portions of the sleeve and thereby holding the cones at proper distances apart.

This design of construction obviously produces a simple and inexpensive bearing a which can be made from sheet metal stampings, that in turn can readily and quickly be assembled to form a cheap yet durable and uniform make of bearingquite as satisfactory for the class of work upon which they are to be used as a bearing made in a more expensive manner.

Having thus described my invention, what I claim and desire to secure by Letters Patcut, isa 1. A roller bearing comprising a tubular sleeve substantially rectangular in cross section and having annular flanges upon its two ends, a bearing cone having a rectangular opening therethrough fitted on each end portion ofthe rectangular sleeve, and

- having openi'n a tubular spacer also having a rectangular opening therethrough fitted upon the rectangular sleeve between the two said hearing cones.

2. The combination with a wheel having a central opening therethrough and race- Ways for balls on either side surrounding the opening, balls in said raceways, a tubular sleeve of angular cross sectional shape, bearing cones to also support the balls and therein to receive the angular end portlons of the sleeve, and means for holding the cones 'at fixed distances from each other upon the angular sleeve.

3. The combination with a wheel having a central opening therethrough and raceways for balls on either side surrounding the opening, bearing cones positioned opposite the raceways, balls between the raceways and cones, a tubular sleeve of angular cross sectional shape upon which the two cones are mounted, and means for holding the cones at fixed distances from each other upon the angular sleeve.

4. A roller bearing comprising a sleeve of angular cross sectional shape having its end portions flared outwardly to form annular flanges, bearing cones having angularly shaped openings adapted to fit the angular portion of said sleeve, said annular flanges adapted to engage said bearing cones, and a tubular spacer on the sleeve between said bearing cones, whereby the cones are held 'in fixed relation on said sleeve and the sleeve is adapted to be fixedly located on an axle.

Signed at Waterbury, in the county of New Haven and State of Connecticut, this 5th day of March, A. D., 1920.
